Prototype Phantom Bodies: Cocker/Angel threaded

I've had these for a while hoping that I could find time to finish them. Best laid plans, eh? What I have here is 3 prototype phantom bodies with cocker barrel threads and angel feed neck threads. The problem with these bodies, what keeps them from being perfect, is that the second boring operation wasn't precisely done. The depth is around 3 hundredths of an inch out of spec. I'll include shims to fix this issue that slide over the valve before the body. Set:
-Body: cocker barrel threads, angel feed neck threads
-Body Clamp: perpendicular 10-32 threaded through holes
-Shim: my embarrassment
